AFS Stream

AFS STREAM – Fluidity Meets Control

The AFS STREAM is inspired by the natural movement of fluids. Light, intuitive and high-performance, it offers effortless power and high efficiency – with full control. The STREAM disappears in flight, letting you fully focus on your line, the water around you, and your sensations – not on your wing.

Designed to shine in freeride, freefly and wave-riding, the STREAM is for all styles of riding – from intermediate to expert. It delivers smooth, well-balanced power that turns into fluid glide and solid acceleration – fast, but always under control.

Key On-the-Water Strengths

• Easy takeoff thanks to early low-end power
• Locked-in profile with strong forward pull for top-end control and exceptional drive
• Balanced, smooth flight behaviour – excellent for freefly, downwinders and surf foil
• Natural tacking – the wing flips naturally through tacks without interruption

UPE FlowFrame™ – Rigidity Meets Minimum Drag

Thanks to its UPE construction (Ultra High Molecular Weight PolyEthylene), the STREAM delivers excellent glide with extremely low drag. UPE allows drastically reduced strut diameters, minimising both weight and drag. The inflatable UPE structure, combined with reinforced Dacron and a dual-weight canopy, ensures the wing holds its shape even in gusty conditions. Less distortion under load means more precise handling, better pumping efficiency and a snappier, more reactive ride. A new canopy-to-leading-edge tensioning system enhances power transmission – instant response, crisp acceleration and high-speed control.

Ultra-Light Trailing Edge for Uninhibited Freefly

The back end of the wing has been refined to the extreme: a lightweight PE ripstop canopy with dual-weight fabric optimises load tension. This ultra-light cloth offers a floating-in-your-hands feel, enabling a natural, fluid flight in the surf. Controlled tension = a lively yet smooth wing, capable of instant response without harshness – ideal for wave riding and transitions.

CLIP-ON Boom – One Boom for Multiple Wings

The Carbon CLIP-ON boom comes in one size for all STREAM surfaces from 3 to 6 m² – also compatible with the AFS D-lite Boom. Riders who already own a CLIP-ON boom travel lighter and optimise their quiver. The redesigned bag fits with and without boom – compact and travel-friendly.

Size Guide

• 3.0 m² – 20–35 kn: maximum reactivity for experienced riders in strong wind
• 3.5 m² – 18–30 kn: all-round strong-wind expert
• 4.0 m² – 15–27 kn: the most versatile entry into the STREAM range
• 4.5 m² – 13–25 kn: freeride and wave in medium wind
• 5.0 m² – 11–22 kn: early takeoff, maximum glide
• 5.5 m² – 9–20 kn: light-wind specialist with strong low-end power
• 6.0 m² – 8–18 kn: maximum surface for heavy riders and light wind
